Abstract

The invention is directed to a detachable fluidisation device for use in a vertical positioned tubular foundation pile having a pile axis and comprising of a central element and radially extending fixing means. The radially extending fixing means can have a first position wherein, in use, the central element is radially fixed to the interior of the tubular foundation pile and a second position which allows the fluidisation device to axially move along the length of the tubular foundation pile. The central element has at its lower end a rotating lower end provided with horizontally extending arms. The arms are each provided with high pressure water injection nozzles and with mechanical cutting elements extending from the arm in the direction of rotation.

Abstract

The invention is directed to a foundation pile (1) comprising a tubular housing (2) having an upper end (3) and an open lower end (4) and wherein at the upper end or near or at the open lower end (4) vibration means are present and wherein at the open lower end means (6) to discharge a fluid into the interior space (20) of the tubular housing and means (7) to discharge a fluid from the lower end (4) of the tubular housing (2) in a direction which has a downward directional component. The means (6) to discharge a fluid into the interior space (20) of the tubular housing have can fluidise the soil present in this interior space.
